	/// Example04: The Electric Potential Due to a Dipole. 
	/// An electric dipole consists of two charges of equal 
	/// magnitude and opposite sign separated by a distance 2a, 
	/// as shown in Figure 25.14. The dipole is along the x axis 
	/// and is centered at the origin.
	/// (A) 
	/// Calculate the electric potential at point P.
	/// V = 2 k_e q a / (x^2 - a^2)
	/// (B) 
	/// Calculate V and E_x at a point far from the dipole.
	/// V = 2 k_e q a / x^2
	/// E_x = 4 k_e q a / x^3
	/// (C) 
	/// Calculate V and E_x if point P is located anywhere 
	/// between the two charges.
	/// V = 2 k_e q x / (a^2 - x^2)
	/// E_x = -2 k_e q ((a^2+x^2) / (a^2-x^2)^2)
